After talking to several users of iOS 4.2 GM and Mac OS X 10.6.5 (public release) it appears that AirPrint functionality does not work. The printing option is definitely still present on the iOS software but it doesn’t actually print what you are telling it to print. On the other hand, it appears that AirPrint is working for users with the iOS 4.2 GM whom have upgraded to Mac OS X 10.6.5 final from one of the betas.
Flickr user TalkaboutDesign has uploaded pictures to his account detailing that AirPrint is in fact working for him with Mac OS X 10.6.5. Because of this, we figure he upgraded from a beta and iOS 4.2 final will be required for AirPrint to actually work. After all, Steve Jobs said that AirPrint wasn’t removed from iOS 4.2 and he would not lie, right?
We’ve heard multiple reports from users that the golden master seed of iOS 4.2 still had a few bugs and because of this, we believe Apple has been fixing up iOS 4.2 the last couple days and has changed some algorithms related to AirPrint. So, hopefully Friday we’ll know the full story as to if AirPrint will work with iOS 4.2’s public release or not.
